FLOOR BRUSH Filed Jan. 6, 1927 Inventor Atto r71 21y Patented Oct. 21, 1930 handle in relation to the UNIT HOWARD J'. HOLTJ'E, O1 WOODCLIIF, NEW JERSEY noon BRUSH Application fled. January 6, 1927. Serial No. 158,381.

The present invention relates to a brush for waxing, scrubbing, cleaning and polishing floors and has for its prime'object to provide a brush of this nature having incorporated therein a liquid wax reservoir for feeding the liquid wax to the floor when desired as the brush is used.

Another very important object" of the invention lies in the provision of a brush of this nature with means whereby the liquid wax is forced from the reservoir to the floor by the relative swinging movement of the brush as, said brush is moved to and fro upon the floor.

A still further very important object of the invention resides in the provision of a brush having a reservoir with a bellows associated therewith and means whereby the operation of the bellows will cause liquid wax to be delivered from the reservoir to the floor during the operation of the brush.

Another important object of the invention resides in the provision of detachable means for engaging the bellows with the handle and is pivotally mounted on the brush so that the swinging movement of the handle in relation to the brush during the to and fro movement of the brush on the floor'will cause the operation of the bellows to deliver the liquid wax from the reservoir to the floor.

A particularly important object of the invention resides in the provision of a structure of this nature which is exceedingly simple, comparatively inexpensive to manufacture, thoroughly reliable and efficient in operation, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in viewas will appear as the description proceeds, the invention resides in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: a Figure 1 is a top plan view of the device embodying the features of my invention,

fFig. 2 is a sectional side elevation there- 0 Fig. showing particularly the ED STATES PATENT OFFICE 3 is an enlarged detail sectional view reservoir and an inverted U-shaped tube associated therewith. Referrmg to the drawing in detail, it will be seen that the numeral head which is of a substantial triangular.

sides converging forthe base is of a curved formation having the wardly to a point and formation to provide a seat 5 denotes a brush or recess as at 6 to receive a conduit 7 having a removable closure plug 8 therein.

The brush head 5 has bristles 10 mounted therein in the usual well known manner or any other preferred manner. The brush head is provided with an opening 9 in which is mounted in any suitable manner a reservoir 11 for holding a quantity of liquid Wax which is poured therein through the conduit 7 which is connected therewith. A plate 12 is fixed to the brush head 5 and another plate 13 is hinged thereto as at 14. Flexible material 15 connects the plates 12 and 13 so as to form therewith a bellows or pneumatic which is denoted generally by the letter with an opening 13 the bellows B, and

B. Plate 13 is provided to permit air to. enter into a suitable valve 13 is associated with the plate 13 and the opening 13 whereby air entering the be ed from escaping therefrom opening 13*. A bracket 16 brush head 5 adjacent the pivotally mounted thereto 112:. A bracket 19'is fixed t e llows B is preventthrough the is mounted on the hinge 14 and has as at 17 a handle to the plate 13 of bellows B and has a laterally extending pin 20. A latch 21 is pivoted as at 22 to an intermediate portion of the handle 18 and is engageable with the pin 20 to lock the bracket 19 in engagement with the handle 18 as the handle 18 is rocked so that when the brush is in use on the floor the bellows or pneumatic will be expanded and contracted. An opening 24 is provided in hinge 14 and downwardly through front of the reservoir thereof is threaded as conduit 27 the longer from near the bottom the leg

the plate 12 adjacent the receives a pipe 25 which depends opening 9 to the 11 and the lower end at 26. A siphon-like of which extends of the interior of the reservoir 11 up through an opening in the front wall thereof and through an opening in the upper portion of the pipe the shorter le then extending downwardly a distance in said pipe 25. An inverted U-shaped pipe 28 has one leg in the reservoir 11 and the other leg exteriorl thereof, the bight or connecting portion t ereof extending through the upper portion of the front wall of the reservoir 11. The bightor connecting portion of this engaged on the exterior end of the U-shaped pipe 28 and the plug 8 is removed from the conduit 7. As the reservoir is freely vented when the plug 8 is removed from the conduit 7, atmospheric pressure will be exerted on the contents of the reservoir. When the bellows is contracted the air that has been drawn therein through pipe 25 and the opening 13 by the expanding of the bellows, is forced down through the pipe 25 therein reducing the ressure in the shorter leg of the V-shaped con uit 27, which is disposed in said pipe 25 so that the atmospheric pressure in the reservoir 11, the conduit 7 being open to the air, will cause the wax to fiow up through the leg of the conduit 27 which is disposed in the res ervoir and down through the shorter leg of the conduit 27 in the pipe 25 so that a certain amount of liquid wax will be delivered to the floor surface over which the brush is being pushed. This flow of wax will stop immediately u on the expansion of the bellows and thus the ow of wax will be intermittent or of a pulsating nature in relatively small quantities and thus may be efliciently worked into the floor to obtain the best results.

If a larger quantity of the Wax is desired the cap 30 may be removed from pipe 28, and placed on the threaded end 26 of the pipe 25 and the conduit 7 closed by screwin plug 8 in place and thus when the bellows is contracted, pressure is created in the reservoir 11 higher than atmospheric. pressure as air is forced through the pipe 25 and conduit 27, as will be ap arent, so that the wax will be forced out t rough the inverted U-shaped pipe 28. The vent 29 provided in pipe 28 prevents the liquid from being siphoned from the reservoir so that only the air pressure from the contracting bellows will force the liquid through the pipe 28 in an intermittent flow.

The advantage in this invention lies in the ability of the operator to supply the right quantity of wax to the floor. It has, hitherto, been the practice to spill wax on the floor and appl abrush separately. Withmyimproved brusll the floor will be supplied with liquid wax in the necessary quantities thereby preventing waste and softening and cleaning the old Waxed surface. Obviously, by disengag ing the handle 18 from the bracket 19 the belloWs may be rendered inoperative so that the brush may be used Without the supply of wax as is desirable, for instance, in using a pad on the brush to take up the excess wax and in polishing.

It is thought that the construction, operation, and utility of this invention will now be apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above de scription. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
